lie it known that l, l-lnixruen Korean-s. a citizen of the German Empire, residing at Essen-on-the-Rulu-, in Germany, have in:

.3 vented certain new and useful lmp-rovements in Cupola (las- Gcnerators, of which the followmgisfii OClllCtttlOIL The object of this invention is to provide improved means for leveling the fuel ina cupola gas generator in such a manner as to produce a fuel surface emission of gas to the eduction pipe. To this end I usein the upper part of a geneu ating' chamber a rotatable gas cduction pipehavii'ig a downwardly directed flared inta lgm end to which a leveling appliance. adapted for the purpose stated, attached. Between the edge of the flared end of said pipe and the wall of the generator} leave justsutiicient space for the fresh fuel to descend from above the flaredpart, ofthe pipe, and l make the wall of the said flared part slope at an angle approximating to the. normal slopcof the fuel at. the top of the charge. The pipe. with its flared part, isrotatetl so as to distribute the fresh fuel evenly around it, to which end I may placeribs-on the flared part. and the descending fuel has a natural tendency to form a cavity under the pipe, the function of the leveling appliance beingflto shape and level the surface of this cavity. The circumference of the latter coincides with the circumference of the orifice at the flared intake end of the pipe. A regular and e'tlicient gas-emission surface is thus insured. though the fuel is fed in later ally of the eduction pipe and of the vertical axis of the generator.

The invention is illustrated in the acconn panying drawing. which is a vertical section of the generator. I

In the drawing, 10, designates the generator chamber or fuel receptacle, which is closed at thebottoin by an ash-pan 11, to which is fixed the stepped grate 12 for the emission of slag or clinker. the pan and grate being rotated by an .ns of Worm gear 13. The gas eduction 4;. take-01f pipe 14: is centrally arranged at the upper part of the generator, and is rotatable, the pipe being for this purpos mounted on a bearing with a liquid seal 18. Shafts 22593, and

bevel gears 24, 25, connectthe pipe 1e to the Worm gear 13. so that the pipe is rotated at a speed hearing a suitable relat on to the -fuelhopper 17 is joined to the'j-wallcf this well adapted for clearing the said edgeof course has a tendor rotation ofthe, grate. An annular chamber-.19, open the bottom to the main generator chamber; is formed. around. the.

pipe 1%,- and the-discharge end 16 of the f chamber- 19. The pipe 1 1' is flared-at its lower end, within the" main chamber, to,

form a hollow truncated cone 29, having ribs; 21 projecting frem its sides. The slope oft; the sides of this cone approximates to' the? normal slope of the fuel at the top of the. charge, and the circumference ofthe cone at: the bottom is so spaced from the wall the main chamber as to leave an. annulargap ust' adequate for the goal to.."pa=$ through. Leveling members ordain e715 fixed across the bottom. of the'cone, these members having a downward parabolic curvature. a H

The charge introduced at 16 from the hopper 17 partly fills the space in the main chamber above the cone 20, this space being.

utilized as a kind of storage chamber, inf. which the fuel 18 pre-heated. The rotating cone 20 evenly distributes the fuel in this space, the distributing action being assisted by the ribs 21. The distributed fpel (l6 scends uniformly through the gap around the lower edge of the cone 20, and after ency to'slide inward, so that there is a natu ral tendency for the fuel to form a cavity below the induc ion pipe. The surface of this cavity is leveled and made regular by the hevelingmenibers'lli. The co e 20 and the leveling members thus coactto produce under the eduction pipe a fuel surface well adapted for the emission of gas to the pipe. It is well known that the provision of such a surface is a highly important factor in the manufacture of gas.
